Features & Product Details

GReddy is proud to introduce a new generation of "Push Type Blow Off Valve", the GReddy BOV FV. The "FV" stand for Floating Valve, and it is this breakthrough in design that produces quicker valve response, increased valve travel, and improved resistance to premature valve lift and boost leak. The unique floating valve design incorporates a revised adjustable dual spring system and diaphragm ventilation, while maintaining the advantages of the previous model's push valve structure and heat resistant silicone diaphragm and valve ratio. This allows the springs and diaphragm to better control the valve and boost. By relocating one spring under and keeping one over the diaphragm, it makes the need for spring pre-load less dependent on idle and light boost situations and more on keeping the valve closed under boost. The result is our best performing GReddy Blow-off Valve yet! Another improvement includes an adjustable, sliding top hat, to adjust the hose fitting location, without complete dis-assembly. The FV also keeps its overall mounting and outlet dimensions, which means it is compatible with the industry standard two-bolt GReddy BOV flange and can easily replace existing Type RS & RZ applications, as well as use the same optional RS and RZ outlet adapters.

GReddy FV Blow Off Valve ( Part Number: 11501665)
Performs well, five minute install on my 2.5L LeBaron 1 year ago
Boise Boost Junkie
After running a cheap bov for almost a year, I was having issues with chopping at partial throttle, boost leak under WOT, and surging on throttle body close. Decided it was time to bite the bullet and upgrade to a name brand unit for the sake of my turbo. I already had the piping and proper flange for a Greddy valve so I opted for the Type FV. I am happy as a clam. Very high quality billet aluminum design, and I love the floating valve setup. It engages flawlessly and was simple to dial in. Needless to say my turbo no longer chops, leaks boost, or surges when I let-off the throttle. The sound is crisp and satisfying. Shipping options were CHEAP and the unit shipped the same day. Bravo RallySportDirect, you guys are top-notch!

  • Q: RHD JDM 1998 Subaru Legacy GTB  Safer4 months ago

    Hey, I was wondering if this will fit my JDM 98 Subaru Legacy GTB. And what kind of issues or problems could it pose that I should watch out for? Do I need to tune my car right after installation for proper performance? And if I need specific brackets or other installation bits would you guys be able to provide them for me???

      A:  This BOV is a universal product meaning that it is not specifically made for any certain application. Unfortunately, we are only able to confirm fitment of any of our parts to USDM models and so we would not be able to confirm that an adapter that we hold would work for your car.
